Overbite Palm is a Gopher client for classic Palm PDAs and mobiles running at least PalmOS 3.5 with at least 4MB of RAM and a network connection. It has not been tested in webOS under Classic.

Overbite Palm is furnished to you under the BSD 3-clause license. The most current release is available from the releases tab.
Install OverbitePalm.prc, plus Plua2RT.prc and MathLib.prc on your device (if not already done so - you can use them if they are already installed on your device for another app). The pilot-xfer utility can do this if you are on a system that does not have Palm Desktop (such as pilot-xfer -p usb: -i OverbitePalm.prc Plua2RT.prc MathLib.prc).
Start Overbite by tapping it in the launcher. It will automatically start your default network connection and access the Floodgap gopher menu. You can change the initial "home gopher" with the analogous option in the app menu.
The Overbite Palm display has a field for the URL (minus the gopher:// portion), and buttons for Go (goes to the entered URL), Back (goes to the previous entry on the history stack), Reload (refreshes the current menu or document) and, when a menu is displayed, Wordwrap (toggles wrapping of long lines in menus). Below the URL field and the control buttons is a scrolling area where the current document or menu is displayed.
Menus are displayed using a scrolling list control. Item types appear at left (such as 1>, which depicts another menu, 0> for a text file, or 7> for a search server). If an item type does not appear for a particular menu item, then it is simply informational text.
While displaying a menu, the Wordwrap button is enabled. Wordwrapping defaults to on or off depending on available memory (as it can necessarily generate a longer list). When wordwrapping is off, long lines are truncated, but each line corresponds to exactly one menu item; when it is turned on, long lines are flowed into multiple lines instead of being truncated, but each menu item may thus take up several lines. You can toggle it on or off by tapping the Wordwrap button. This setting is stored as a preference. On systems with low memory, you may be required to restart the application when the setting is changed.
When a line in the menu list box is tapped, Overbite Palm displays a dialogue box with the entire line (as screen size permits) and, if it is a link to another item or menu, displays the destination, and asks if you want to go there. If you decline, navigation is cancelled. If it is merely informational text, just tap OK when done reading it.
Text files are displayed using a scrolling text widget. Text is automatically wrapped by the operating system.
If you navigate to an item pointing to a search server or other interactive service, Overbite Palm will ask you for a parameter or command to send.
You can change and visit the home gopher or one of three built-in bookmarks using the corresponding choices in the app menu. Shortcuts are available for quickly visiting them.
On Fossil and Abacus Wrist PDAs, the rocker, up/down and back buttons are live. If you press back on the root menu, it will return you to the Launcher. You will need to install networking software; read this blog post for more information.
Menus and text files may be truncated if you have insufficient dynamic heap. This is mostly an issue for 68K Palms, where only a few hundred kilobytes total may be available (ARM Palms with Palm OS 5 should have no issues), and Palms with less than 4MB of RAM will not have enough dynamic heap to run Overbite Palm at all. To see how much memory Overbite Palm thinks is available, select About Overbite Palm from the app menu and scroll to the bottom. It will display the OS version and free and total heap space.
There is a hard limit on the amount of text that can be shown in the scrolling text widget; empirically this appears to be 32K, regardless of the amount of heap.
Overbite Palm does not currently support CSO/ph, images, HTML (displayed as text), Telnet/TN3270, hURLs or downloads (either to internal RAM or to the SD card).
Overbite Palm is written in Plua 2. You will need the plua2c cross compiler to build it. With the compiler installed, just type make and the .prc will be generated.
make run will run it within an instance of your preferred Palm emulator. You may need to edit the Makefile to point it to your emulator or use a different command line (the default is to run POSE through QEMU).
Remember that your device or emulator must have Plua2RT.prc and MathLib.prc to run the generated client.
